- BJBerenice JuarezAug 14, 20265.0I had previously contracted four separate HVAC companies to help address my parents’ condo HVAC issues. None of them helped, none of them cared, and all of them charged me even though the issue was never fixed. Bardia with Zagros finally solved the problem. He was professional and so thorough and he took the time to actually explain to us what was wrong. It is sad in this day and age you just don’t get service like this anywhere. If you have an HVAC issue, I cannot recommend this company enough!
- RWRob WittmanJul 6, 20265.0Zagros installed a mini-split on my first and second floors, works great and bring both cooling and heating at the right place and right time.
- RJRufus JohnsonJun 26, 20265.0They replaced our AC system in the summer on short notice. Great price and excellent customer service, from the technicians to the admin to the management. Very pleased. 10/10 would recommend.
- JFJohn FindleyJun 23, 20265.0Zagros is reliable. We had a maintenance contract with them. Because we had a contract, whenever any problem occurred Zagros was there that same day to resolve and repair the problem.
- JZJudy ZhuJun 21, 20265.0We have been using Zagros Heating & Air for our HVAC repairs, installation and maintenance over 10 years. This is the HVAC firm we trust they do good work and with great price. Highly recommend. J.Z.
Frequently Asked Questions About Zagros Heating & Air Conditioning
What areas do you serve?
We serve Sterling, Ashburn, Herndon, Reston, Fairfax, and the surrounding Northern Virginia communities. If you are uncertain whether your location falls within our service area, contact us and we will confirm. If your address is slightly beyond our standard coverage zone, we will make every effort to assist you or provide a qualified referral.
What services do you offer?
We provide comprehensive HVAC and water heater services for residential and commercial properties. Our offerings include system repairs, replacements, new installations, preventive maintenance, diagnostic evaluations, indoor air quality improvements, and water heater services. Whether your equipment is producing unusual sounds, underperforming, or requires scheduled maintenance, we will identify the issue and deliver an appropriate solution.
Do you offer emergency HVAC service?
Yes. We understand that heating and cooling failures often occur without warning. When you experience an urgent situation, we respond promptly to restore comfort to your home or business as quickly as circumstances allow.
Why is HVAC maintenance important?
Regular maintenance allows your equipment to operate efficiently, extends its service life, and prevents unexpected failures during peak demand periods. Scheduled service enables us to identify minor concerns before they develop into costly repairs. Proactive maintenance is a more economical approach than addressing breakdowns after they occur.
Do you offer maintenance plans?
Yes. The Zagros Peak Performance Plan includes three service tiers: Basecamp, Ridge, and The Summit. Each level provides ongoing maintenance, cost savings, and priority service based on your selected coverage.
How often should I service my HVAC system?
We advise scheduling service twice annually: once prior to the cooling season and once before the heating season begins. This schedule ensures your equipment is prepared for periods of high demand. Spring and fall are typically the most appropriate times for these inspections.
Why is my AC blowing warm air?
Several factors may cause this condition, including insufficient refrigerant levels, a contaminated evaporator coil, inadequate airflow, electrical malfunctions, thermostat issues, or internal component failure. Some situations require straightforward corrections, while others indicate more significant system concerns. We can perform a diagnostic assessment and recommend the appropriate course of action.
How do I know if I need a repair or a replacement?
This determination depends on system age, overall equipment condition, repair costs, and failure frequency. If your unit is aging, operates inefficiently, uses phased-out refrigerant, or requires repeated repairs, replacement may represent a better long-term investment. If the problem is isolated and the equipment remains sound, repair may be the appropriate solution. We will present your options transparently so you can make an informed decision aligned with your budget and requirements.
What should I check before calling for service?
Before contacting us, verify your thermostat settings, ensure the circuit breaker has not tripped, confirm the system is receiving power, and inspect the air filter. A restricted filter can cause numerous performance issues. Additionally, confirm the thermostat is set to the intended operating mode. Many service calls result from settings that were inadvertently changed.
How long does it take to install a new HVAC system?
Most residential installations are completed within one day, though actual duration varies based on system size, home configuration, and whether ductwork modifications or other adjustments are necessary. More involved projects may require additional time, particularly when system upgrades or structural modifications are involved. We complete installations efficiently while minimizing disruption to your property.
